    I know the basic physics involved, (Bernoulli, airfoils) and it still amazes me that wind can do that.

    Physicist asks God, “Why is there turbulence?”

    G: “So we can mix drinks.”

    Yeah, but you need to recognize the Satanic parts of physics, too.
    Just when you think you understand chaotic-looking processes like turbulence, Satan introduces vortex-shedding and flutter resonance.

    Resonance is nature’s way of hittin’ an engineer’s knuckles with a ruler when they begin to doze and think the math don’t really make no nevermind in real-life.

    I’ll put an explanatory vid link for vortex shedding, flutter, and resonance up top

    ^ resonance, ain’t that them frequency waves the herbal life guy was always going on about?

    Fun fact: The Tacoma Narrows bridge sections on the floor of the Puget Sound are the largest man-made structure ever lost at sea.
